Booster Transformer: Sometimes it is desired to control the voltage of a transmission line at a point far away from the main transformer. This can be conveniently achieved by the use of a Booster Transformer…
Statistical Process Control Interview Questions and Answers: 1. What are the sources of variations present in various processes? Ans. Equipment Material Environment Operator 2. What is a rational subgroup? Explain. Ans. The data that are…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are increased. The increase in the…
Transformer Cooling System: Transformer Cooling System (Large Units) - Basically, there are two seats of losses in a transformer namely: Core, where eddy current and hysteresis losses occur (caused by alternating density). Windings (primary and…
Antenna Definition: The Antenna Definition is a quick review of impedance matching (basic transformer theory) and resonant circuits. It was pointed out that maximum power transfer could be achieved only when the source matched the…
Transistor Construction Techniques and Performance: The following are Transistor Construction Techniques and Performance are as follows, Current Gain: Good current gain requires that most charge carriers from the emitter pass rapidly to the collector. So,…
Electron Emission Interview Questions and Answers: 1. What is Fermi level? Ans. The maximum energy that an electron in a metal has at the absolute zero temperature is called the Fermi level of energy and is…
Voltage Divider Bias Circuit: For the self-bias circuit, it was seen that increasing the resistance of RS brings ID(max)Â and ID(min)Â closer together, but that increased RS values result in lower ID levels. As will be demonstrated,…
What is MOSFET Resistor?: DE-MOSFET can be employed as a resistor by connecting the gate to the source, as shown in Fig. 13.91 (a), so that gate-toÂsource voltage VGSÂ is zero. E-MOSFET may also be employed…
AM Detection using PLL: AM Detection – A PLL can be used to demodulate AM signals as shown in the Fig. 2.133. The PLL is locked to the carrier frequency of the incoming AM signal.…
